Answer:
53 yards
Step-by-step explanation:
Let w represent the width. Then w+2 is the length, and the perimeter is ...
P = 2(L+W) . . . . . . . . . formula for the perimeter of a rectangle
216 = 2((w+2) +w) . . . . fill in values for length and width
216 = 4w +4 . . . . . . simplify
54 = w +1 . . . . . divide by 4
53 = w . . . . . subtract 1
The width of the rectangle is 53 yards.
If u can’t find the answer here u can always use the Socratic app
Cos A = (589^2 + 513^2 - 741^2) / 2 x 589 x 513 = 61,009 / 604,314 = 0.1010
A = cos^-1(0.1010) = 84.2 degrees
Let the depth of the submarine be x, then
sin 84.2 = x / c = x / 513
x = 513 sin 84.2 = 510
Therefore, the depth of the submarine is 510.
